MAGNILyser: Next-Generation TB Sample Preparation Through Inductive Heating and Mechanical Lysis

David Erickson of Cornell University in the U.S. will develop a device for heat inactivation and mechanical lysis of Mycobacterium tuberculosis from patient samples to enhance TB diagnosis. A prototype device will be engineered, using a non-TB Mycobacterium for testing as a proxy. The device combines an alternating magnetic field and magnetic beads to inductively heat inactivate bacterial samples and actuate lysis by a bead-beating mechanism. The protype will be pilot tested in a collaboration at the Infectious Diseases Institute in Kampala, Uganda where patient samples with presumptive TB will be processed with the standard protocol for TB diagnosis and in parallel with the prototype.
